[Slacko 5.7, full hard-drive install]
There was some problem with "pet" files not launching, so I rebooted. Puppy couldn't get into the GUI. I reinstalled without "Wiping" from the CD. Now Puppy boots fine; but doesn't "Shut Down" or "Reboot" by clicking on the menu buttons or pushing the power button and confirming.

If it's complicated to try to fix this - just tell me how to backup the applications; so I could reinstall and wipe or even format the partition.
Thanks.

This is a way to repair a full install.
This only works for full installs.
Boot with the live CD of Slacko
Use boot option puppy pfix=ram
At desktop select install icon
Select button to run Universal installer
Do a full install of Slacko to the same location as the none working full install.
Very important
During the setup for the full install you will get option to upgrade
Choose that option upgrade
Do nothing to bootloader. Old settings will still work.
When installer is finished remove CD
Reboot to the full install.
(Because you where running the live CD, it will ask about making a save file. Say no.)_________________I have found, in trying to help people, that the things they do not tell you, are usually the clue to solving the problem.

BigPup - I don't think it was the packages. I found them on the net. The application was "netsurf-2.6". There were 3 PET files. I think that they didn't work because of some random problem; maybe because the OS ran for a long time. I think so because after rebooting - I was able to install it; and it worked. Moreover - I already uninstalled it, and the same problem continued.
I think the problem is because I didn't install them till the end and/or powered-off forcefully.

The partition is ext4.
I pretty much tried what you describe; but without starting Puppy in the PFix mode; so I'll try that.

The two first files you mentioned - exist.
In the file ".jwmrc" - there is the line - <Program label="Shutdown" icon="shutdown48.png">/usr/sbin/logout_gui</Program>
The word "reboot" - does not exist in the document.

n the file ".jwmrc"
The word "reboot" - does not exist in the document.

That is correct.
Slacko 5.7 uses a logout menu

In Slacko 5.7 menu->Shutdown runs logout_gui

The file is at /usr/sbin/logout_gui

You could try and replace the logout_gui file with the one from the Slacko 5.7 iso file._________________I have found, in trying to help people, that the things they do not tell you, are usually the clue to solving the problem.

If you did power off in an abnormal way, there is a chance you may have some file system corruption of the partition.

Run the program Gparted and have it do a check of the hard drive.

To use Gparted:
Boot with the Puppy live CD
At the Puppy boot screen hit F2 key.
Use the boot option puppy pfix=ram.
This keeps the hard drive from being mounted.
Hard drive can not be mounted for Gparted to work.

In Gparted
right click on a partition
Select check
If it finds anything wrong it will correct.

If you have more than one partition on hard drive
run a check on all of them.

Remove the live CD
Reboot
Because of the way you are running with the live CD. You will be asked about making a save file.
Choose no._________________I have found, in trying to help people, that the things they do not tell you, are usually the clue to solving the problem.

WOW, nothing worked.
I think that I couldn't boot in the "pfix=ram" mode; it said something about not being able to load something, I think. It did boot; I just don't know if in that mode.
GParted couldn't check the disk. There was an option to save the error details; but it didn't actually save it where I tried.
I replaced the file "logout_gui"; didn't change anything.
When I run "wmpoweroff", it says - "kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec ... or kill -
1 [sigspec]".

Did you enter puppy pfix=ram_________________I have found, in trying to help people, that the things they do not tell you, are usually the clue to solving the problem.

For partitioning I would suggest you use the Gparted live CD or USB that you can get from here.
You can download a free version to make your own Gparted live CD or USB.
It is up to date and specifically made to run Gparted.

If you are saying you tried to use the Gparted live CD.
Tried to do a partition check using Gparted.
Gparted could not check the partition and gave you an error message.

Can you remember what the error was?

Even if you can not remember all of the error. In general what was it?

This is going to be the clue to figure out what is going on.

If Gparted is refusing to do a partition file system check it usually indicates there is something really wrong with the partition.

It could be telling you it found something wrong and is asking if you want to correct or telling you to do something first, before it can check._________________I have found, in trying to help people, that the things they do not tell you, are usually the clue to solving the problem.
